摘要
基于随机介质中波的辐射传输理论,采用蒙特卡罗法,数值模拟了满足对数正态分布的水溶性气溶胶和烟尘气溶胶组成的多分散系外混合城市气溶胶的消光系数。与文献数据进行了对比,验证了采用离散组分抽样的蒙特卡罗模拟方法的正确性。分析了外混合气溶胶中透射率和反射率随入射波波长、入射角余弦及光学厚度的变化关系。比较了不同混合比下外混合气溶胶的传输特性。数值计算结果表明,波长的减小将导致外混合气溶胶的透射率降低反射率升高。同时,外混合气溶胶总体表现出的传输特性与组分间存在十分敏感的关系。
Abstract
Based on wave radiation transmission theory in random medium and Monte-Carlo method,the transmission characteristic of external mixture of aerosol which is composed of water soluble and soot with lognormal distribution is studied.The dependence of extinction coefficients of urban aerosol on incident wavelength is numerically simulated,which is compared with reference data.The accuracy of the discrete sampling Monte-Carlo simulation method is proved.The effect of incident wavelength,the cosine of incident angle,and optical thickness on the transmittance and reflectivity of laser in mixture aerosol is analyzed.Comparison is given between the external mixtures of aerosol with different mixing ratio.The numerical results show that the decrease of wavelength will lead to reduce transmission characteristic of external mixture aerosols and increase reflectivity.And the total transmission characteristic of external mixture aerosol is sensitive to its composition.
